Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nano carbon fiber infrared heating lamp for heating greenhouses,

The present invention relates to a method for installing a nano-carbon fiber infrared heater for heating a fruit and vegetable seedling and greenhouse, and more particularly, to a proper installation height and spacing of a nano carbon fiber infrared heating for heating a greenhouse of fruit and vegetable seedlings.

In general, artificial light sources are widely used in plant cultivation. Plants usually grow through the action of chloroplasts synthesizing carbohydrates, such as starch, from carbon dioxide and water with the power of sunlight. Photosynthesis, which converts light energy into chemical energy, is the most important part of plant growth. However, according to the researches so far, the photosynthesis action of the plants and the growth rate thereof are not made indiscriminately for all wavelengths of light, but more particularly at specific wavelengths.

Therefore, conventionally, a light source such as a light emitter diode (LED) capable of intensively irradiating light of a specific wavelength range for promoting photosynthesis is used instead of an illumination device such as an incandescent lamp or a fluorescent lamp for irradiating light of all wavelengths Techniques for use in plant cultivation have been proposed. Such a conventional lighting apparatus having an LED light source is disclosed in, for example, a registration document of Korean Patent Registration No. 10-0902071, " method and apparatus for plant-based cultivation using an LED lamp " by Kast Engineering Co., Publication No. 10-2004-0010426, "Dye Plant Plant and its Apparatus Using LED Light Source", and Patent Registration No. 10-0879711, Chang Woo-In et al., Entitled "LIGHTING DEVICE WITH FLOOR LED" .

However, the lighting apparatuses for plant cultivation using these conventional LED light sources are configured such that blue light and red light are blended in a fixed ratio, and light-off is repeated with a pulse cycle at which the rate of photosynthesis is maximized.

However, it is preferable to control the wavelength range of the light source in various ways such as promoting photosynthesis as well as promoting morphogenesis and flower bud differentiation according to the species, or depending on the growth period of various plants such as seedling, differentiation, Do. Since the necessary wavelength ranges are different depending on the plant growth period, there is a problem that optimal plant cultivation can not be achieved with only the lighting apparatus having the above-mentioned conventional fixed blending ratio.

Therefore, it is necessary to determine the optimum conditions for effective plant cultivation by investigating the plant height, acceptance length, root length, light weight, foliage, leaf width, leaf area, fresh weight, dry matter, fidelity, leaf number and chlorophyll content of fruit and vegetable seedlings according to wattage and installation method. It is a very important invention to investigate the growth conditions of fruit and vegetables.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention and the manner of achieving them will become apparent by reference to an embodiment which will be described in detail below with reference to the accompanying drawings.

The infrared wavelength energy of the nano carbon fiber infrared heating or the like is such that the temperature of an object reflected in an infrared ray such as a crop or a medium is raised first and the heat radiated by the object raises the ambient temperature without raising the temperature of the air directly to be.

In addition, important temperature-related factors in greenhouse crop cultivation are temperature, rhizosphere temperature, daily average temperature and plant temperature, and plant temperature is known to be important compared to temperature.

The nano carbon fiber infrared heating increases the leaf temperature, the growth temperature and the fruit temperature of the plant by about 1 to 2 DEG C, and the growth and temperature are improved by the increase of the growth point temperature.

Also, by increasing the accumulation temperature, it is possible to ship early due to the faster harvesting speed of 2-4 days, and the yield of strawberry can be doubled.

In addition, it maintains the same humidity as the existing greenhouse and removes the condensation of the internal crops in the greenhouse to inhibit the growth of pests (eg, white powder, aphid, and gray mold). Three to five days after the actual installation, there was a case in which white powder, gray mold was dried, and aphids were suppressed.

In addition, it is possible to generate farm income by reducing the cost of farmhouse operation and promoting crop growth with alternative heat source (fuel cost reduction) compared to high oil price, and it can improve farmer's competitiveness by saving 70 ~ 80% compared with the heating cost of horticultural crops.

In addition, the emission of infrared radiation without burning oxygen could significantly improve crop color and development through greenhouse air purification.

Table 1 below is a table comparing the heating costs of the rose greenhouses according to the heating method. When comparing the heating cost of hot water boiler using non-oil oil to the control, it can be seen that the heating cost saving rate of the farmer installing nano carbon fiber infrared heating is 70.9%, and the electric heater and the bunker c oil are used as hot water boiler It can be seen that the installed farms saved 58% and 5.6%, respectively. Accordingly, it can be seen that the heating cost reduction rate of the nano carbon fiber infrared heating used in the present invention is very high.

As shown in Figs. 1 to 3, the nano carbon fiber infrared heating, which affects plant production, is optimally optimized so that energy can be supplied to plants in the most effective manner.

First, FIG. 1 is a photograph showing the nano carbon fiber infrared heating used in the experiment in a greenhouse.

Next, FIG. 2 is a graph showing the direct measurement of the optical wavelength such as nano-carbon fiber infrared heating with wattage values 700 W and 900 W used in the present invention. As shown in FIG. 2, the nano-carbon fiber infrared heating was measured to have a wavelength of 650 to 1,050 nm.

When the infrared heating of 650 to 1,050 nm is used, the temperature of an object to be illuminated in infrared rays such as a crop or a medium is raised first, so that the heat radiated by the objects raises the surrounding temperature, The leaf temperature, the growth temperature and the fruit temperature of the seedlings are increased by about 1 to 2 ° C., so that the power of the flower is improved due to the increase of the growth point temperature. Also, by increasing the accumulation temperature, it is possible to ship early due to the faster harvesting speed of 2-4 days, and the yield of strawberry can be doubled. By replacing high oil prices with alternative heat sources (reducing fuel costs), it is possible to generate farm income by reducing farm management costs and growing crops, and by reducing the heating cost of horticultural crops by 70 ~ 80%, farmers will be able to improve their competitiveness.

As shown in FIG. 2, the nano carbon fiber infrared heating and the like used in the present invention is characterized by having a wavelength of 650 to 1,050 nm and a wattage of 700 W and 900 W. As shown in Figs. 3 to 7 and Tables 2 to 3, it is preferable that the optimum installation height of the nano carbon fiber infrared heating or the like is 100 to 130 cm with respect to the fruit and vegetable seedling, and as shown in Figs. 8 to 12, Or the like is preferably 40 to 60 cm.

The standard of the bed shown in Fig. 3 is 1.2 m X 2.4 m.

In order to heat the watermelon seedlings, the temperature can be maintained at 22 ° C from 9:00 AM to 6:00 PM and 20 ° C from 6:00 PM to 9:00 PM, and the temperature of the nano-carbon fiber infrared heating lamps The experiment was carried out by placing all of them in the height 3 treatment (70cm, 100cm, 130cm from the bed) and the Wattage 2 treatment (700W, 900W).

The nano-carbon fiber infra-red heating and other suitable height test were graphically shown in Figs . 4 to 6 and Table 2 by performing environmental examination including the inside temperature of the greenhouse, the leaf temperature of the plant, the brightness and the thermal image.

Next, FIG. 7 is a graph showing the photosynthetic rate of watermelon seedlings according to wattage and height of the nano-carbon fiber infrared heating. The photosynthetic rate can be measured through the rate of photosynthesis according to the concentration of carbon dioxide generated in the watermelon seedlings. 7, 900W nano carbon fiber infrared heating is 100cm, the highest photosynthetic rate, 700W nano carbon fiber infrared heating is installed at 100cm, 700W nano carbon fiber infrared heating is installed at 130cm , 900W Nano Carbon Fiber Infrared Heating, etc., 70cm Nano Carbon Fiber Infrared Heating, 70cm Nano Carbon Fiber Infrared Heating, 130cm, .

In addition, about 80% of the energy generated from nano carbon fiber infrared heating for the heating of vegetables and seedlings in the greenhouse is infrared wavelength, and the light intensity is not considered to be a level that affects the plant growth and photosynthesis. The temperature change of the plant after turning on the nano carbon fiber infrared heating lamp was found to be able to increase the temperature of the plant in the earliest time in the 70 cm height treatment. The watermelon grafted seedlings showed the shortest length and the shortest length in the height of 900W and 70cm height, and the maximum root length was not significantly different according to the wattage and height of the nano carbon fiber infrared heating. Leaf area, leaf area and leaf number were high in 900W and 100cm height, and compactness and chlorophyll (SPAD) values were effective in 700W 130cm height treatment. In addition, the photosynthetic rate of watermelon grafted seedlings was significantly higher at 900W 100cm height treatment.

Therefore, cultivation of fruit and vegetable seedlings was most effective when the heating height was 100 to 130 cm, and it was found that the most effective cultivation was performed when the wattage was 900 W. Therefore, 900W of nano carbon fiber infrared heating was 100 To 130 cm.
